Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641122, here are decompositions:

29 + 8641093 = 8641122
43 + 8641079 = 8641122
59 + 8641063 = 8641122
173 + 8640949 = 8641122
211 + 8640911 = 8641122
233 + 8640889 = 8641122
239 + 8640883 = 8641122
251 + 8640871 = 8641122

Showing the first eight; more decompositions exist.
